Thanks again for the response, Phil ... I've seen a few videos showing this setup move a 5er around, but I still kind of cringe, envisioning the tug walking out from under the kingpin, with just the vertical pipe, and then think that if it doesn't, it must be applying a lot of push force with the braces to the landing gear. Maybe it's just an over-active imagination on my part.
I envision using a tripod or 4 legged stand that spreads out the load and stabilizes the power tug, but apparently I'm over-analyzing the situation.
I'll look at the Power Caster a little closer.
re: wintersun - which brand unit did you go with?
I do have a spare aircraft tug (12v battery powered) in the hangar that I keep toying with re-purposing, but it's not built to carry any kind of weight load - simply a "push-me pull-you" affair.
The tube is only really to carry the pin, the arms to the landing gear are what pushes/pulls the FW, and what need to be stout enough to do that. You could probably modify the tug or simply pull the tug motor and transmission off it and fab something heavy enough to hold the weight of the pin and install the tug motor on that. Personally, I'd build something with much larger tires both for traction and for floatation if on grass or dirt.
